It helps students become aware of security aspects involving single computers or a network of computers connected to a central main server. Students who want to make a career in computer security can participate in standard security courses offered by schools or online computer security courses offered by different institutes.

Elementary knowledge of computers is essential to join in on any computer security course. Computer security lessons are imparted at a DOS (disk operating system) level. Students are given a DOS primer that can be studied before starting the course.

Students who enroll for computer security courses need to have a Pentium 300 MHz PC, with operating systems configured with Windows 95 or newer versions of an operating system to receive online study material and to complete practical tests. It is also important to have a spare hard drive that holds eight hundred megabytes to two gigabyte, a supply of HD 3½-inch diskettes, a printer and a modem with an Internet connection. Minimum software requirements include computer security utilities (provided with enrolment), a data sniffer (provided with enrolment), quick view plus, Norton utilities and Norton Ghost.

Enrolled students are provided with study modules on a variety of computer security topics. Some of the topics include operating systems, formal methods for information security, cyberspace laws, software engineering, network security, database systems, algorithms & applications (cryptology), information security audit controls and distributed computing security.

Advanced computer security tools are costly and used by most organizations to protect critical data, such as credit card numbers, login passwords, transaction passwords and others. If they are not protected, distortion may occur and lead to financial losses running into thousands of dollars. It also reflects upon the reputation of the organization with respect to providing security to customers.

Computer schools provide all necessary skills for becoming a trained computer security expert. However, it is always advisable to remember that certification alone is not enough to be accepted as a computer security expert. A combination of knowledge and experience is also necessary to get recognition as a computer security expert.

This statement confronts the issue concerning the role of teachers. Although there are advantages to computer and television learning, this kind of learning is considered supplementary to teachers in the classroom.

Computer learning is an engaging tool allowing children to experiment with creative programs at their own pace without additional pressure. Children can work exclusively from their own worlds without a teacher telling them what to do. Therefore, computer learning is excellent for children’s motivation and allows them to question deeply their subject matter. Also, the computer offers a creative variety of programs on different levels and so, computer learning is not entirely boring. From the moment children flick on the computer screen, they can learning Math by working out the answers through a competition match with the computer. This method of learning can be a lot more motivating and challenging than children doing Math exercises in the classroom and for homework.

Also, with computer learning, there are no outside pressures or influences. The teacher does not make personal judgments or evaluation. Computer learning allows for the evaluation to be on the process and not on the person or on the product. By not being evaluated or criticized, children engage their minds and advance at their own pace without the teacher saying, “That’s not good enough” or “You could have done better on that Math test. You know the material.”

Computer learning is suitable for all levels and ages. It is an organized and well structured learning tool. With the rapid pace of technological development, a computer is also a sophisticated learning tool. There are computers with touch-tone screens, computer that talk and sing, computers with three dimensional graphics, and so on. More and more emphasis is being placed on computer knowledge as a prerequisite for many jobs. Some jobs simply require a simple understanding of how a computer works but children can and should have some computer exposure at an early age to prepare for their future.

However, teachers possess fundamental and important qualities, which computers do not possess, and are essential for a child’s learning process. one primary and necessary quality is personal interaction. When children cannot computer a certain math problem or they don’t feel well, the teacher feels it. The teacher has the ability to attempt to help them. Although the computer has been built and programmed by human beings, a computer is still not human. A computer cannot ask why a child cannot do a Math problem and offer advice on how to tackle the problem. This basic fact still explains why teachers are still needed in the classroom.

After all, human beings are smarter than a computer they are the ones who designed it. All the computer knows has been programmed and cannot think and sort problems out emotionally and intellectually. Children still need the classroom environment because of the student-teacher interaction and the relationships with other children. Therefore, it can be concluded that computer learning is user friendly yet supplementary, and impersonal.

Teachers may not be as technologically sophisticated as computers, but they certainly can be creative within a group framework. They don’t necessarily have to ask close-ended questions and bore the class to fulfill their roles as teachers. Teachers can and should allow learning to be enjoyable and stimulating like the excitement children feel when they flick on a computer. For example, a teacher has the option unlike the computer, to organize a project using several groups to ask true and false questions about the environment using the Internet to search for information. The winning team with the most points receives a prize. Not only do the children enjoy these types of mini-type research projects, but they are also benefited with knowledge about the environment as well. unlike the computer, the teacher, by working with the groups, allows for elements such as humor and teamwork together with the feeling of accomplishment and self-satisfaction to seep into the children’s learning.

Although computer learning can be stimulating, fun and accessible to children of all ages, levels and interests, it is not a substitute for teachers. Teachers permit and allow for personal interaction which is essential for a child. Also, teachers can be just as creative by organizing fun learning projects for the class. Learning should be an enjoyable and enriching process and cannot be completed alone without the presence of a teacher. Computer then, are only secondary to the learning process.

He owned a number of transport companies, textile mills and toy manufacturing companies. He also owned a few shipping lines. Although Kelly was a very busy person he had a fascination. He simply loved to play chess. He used to play chess with his dear friend Morris Tillet on a regular basis. However, the sudden premature death of Morris broke his heart and he fully concentrated in his business in later years.

Kelly visited a computer exhibition in 1979, twenty-five years after his friend’s death. The computers on display impressed him. What fascinated him most was that computers can play chess. His fascination for chess was rekindled. He ordered a computer immediately. The computer was delivered to his house within a month. Kelly placed the computer in his study. He had not forgotten his friend though. He placed a bust of Morris Tillet on the computer.

Kelly programmed some great chess moves in the game. He became glued to the game from the very first day. He noticed that the computer played back according to the famous moves invented by an eighteenth century french grandmaster, the favorite moves of this dear friend. Kelly played for three long hours and became tired and exhausted. He went over to disconnect the plug. A surprise was waiting for him. He had forgotten to plug in the computer. The computer worked without electricity!

Kelly did not have much knowledge about computers. However, he could understand quite well that a computer is not supposed to work without electricity. He informed the computer company about the incident. The next day the mechanic came and listened to him. “Incredulous!” the man replied. “A computer cannot play on its own and the moves have to be programmed, let alone working without electricity”, the man continued.

The computer was from a well-known company. The company became worried about their reputation and provided him with a new computer. The new computer was also provided with a chess game having twenty-two simple and sixty complicated chess moves. Kelly decided to publish a new chess move in a local newspaper. As soon as he worked out the move in the computer, the machine started to play back on its own. He became furious and turned the computer off. His fury turned into astonishment very soon. The computer was still working. He disconnected the plug, but, the computer went on displaying the last move on the monitor. Kelly, out of curiosity, made another move.

He suddenly remembered the game he played with Morris on 12th April, 1952. That is a game he will never forget. A strong coincidence took place during that game. Both of them made the same move. The computer did the same thing twenty-eight years later. He informed the company. A team of engineers came and checked everything thoroughly. They took the sculpture away for further investigation. Curiously, the computer worked alright that night.

The experts did an x-ray of the sculpture and carried out many other tests. However, none of the tests did yield any result. The bust was returned the next day. The computer started with all the spooky stuff all over again. The computer experts could never give any satisfactory explanation to the incident. The believers of the supernatural claimed that Morris’ soul used Kelly’s mental power to run the computer. However, this is off-course no scientific explanation. The above tale remains an unsolved mystery till date.

The Z1 originally created by Germany’s Konrad Zuse in his parents living room in 1936 to 1938 is considered to be the first electrical binary programmable computer

The first digital computer

Short for Atanasoff-Berry Computer, the ABC started being developed by Professor John Vincent Atanasoff and graduate student Cliff Berry in 1937 and continued to be developed until 1942 at the Iowa State College (now Iowa State University). On October 19, 1973, US Federal Judge Earl R. Larson signed his decision that the ENIAC patent by Eckert and Mauchly was invalid and named Atanasoff the inventor of the electronic digital computer.

The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons. Although the Judge ruled that the ABC computer was the first digital computer many still consider the ENIAC to be the first digital computer.

Because of the Judge ruling and because the case was never appealed like most we consider the ABC to be the first digital computer. However, because the ABC was never fully functional we consider the first functional digital computer to be the ENIAC.

The first stored program computer

The early British computer known as the EDSAC is considered to be the first stored program electronic computer. The computer performed its first calculation on May 6, 1949 and was the computer that ran the first graphical computer game

The first personal computer

In 1975 Ed Roberts coined the term personal computer when he introduced the Altair 8800. Although the first personal computer is considered to be the Kenback-1, which was first introduced for $750 in 1971. The computer relied on a series of switches for inputting data and output data by turning on and off a series of lights.

The Micral is considered the be the first commercial non-assembly computer. The computer used the Intel 8008 processor and sold for $1,750 in 1973.

The first workstation

Although never sold the first workstation is considered to be the Xerox Alto, introduced in 1974. The computer was revolutionary for its time and included a fully functional computer, display, and mouse. The computer operated like many computers today utilizing windows, menus and icons as an interface to its operating system.

The first PC (IBM compatible) computer

In 1953 IBM shipped its first electric computer, the 701. Later IBM introduced its first personal computer called the “IBM PC” in 1981. The computer was code named and still sometimes referred to as the “Acorn” and had a 8088 processor, 16 KB of memory, which was expandable to 256 and utilizing MS-DOS.

The first PC clone

The first PC clone was developed by Compaq, the “Compaq Portable” was release in March 1983 and was 100% compatible with IBM computers and software that ran on IBM computers.

Would you also like to learn about computers all on your own? I know you do! But you probably don’t know how or where to start from. Don’t worry! After reading this article, you’ll discover how to learn computer on your own faster.

There are so many ways to acquire basic computer training faster all on your own. But some of them are naturally designed to hinder your ambition to learn how to use a computer faster. It all depends on the method you choose for your learning.

The most common reason why most people find it very hard to learn new computer science topics or learn basic computer skills faster on their own, is because they choose to start at first, trying to learn to use a computer on their own from a text book/books.

Another common reason that secretly affects most new learnners’ ability to get computer basic training or learn about computers faster, is that they try to learn how to use computers from a friend or family member, whom they thought or believe that knows about using computers very well. But unfortunately, that person may just know very little about computers. He or she eventually ends up passing the wrong basic primary skills to them. This can secretly affect your ability to master computer science skills faster on your own.

The best method for learning how to use computer or learning new ‘Computer Science Skills’ faster, is through the use of computer training Video lessons or Video tutorials. This method is, without doubts, the best method for non-regular students especially, if you don’t have enough time for learning your new skills. And it’s also good for students, who want to speed up their learning faster and to be ahead of other students.

Another important thing you must not forget to consider, before choosing the right product to buy for your studies is the final out-put of the video training product you intend to buy. Most basic computer training video lessons on sale on the internet and on most shops are recorded on just Audio CDs/CD-ROMs. This can limit your chances of learning computer science topics faster on your own, if you don’t have a personal computer at home. But if you can find one that’s on a simple DVD, it’ll be a better option for you. You’ll be able to learn from your home DVD player as well as from your computer (if you’ve got one at your home).

So if you would like to learn about computers basic training faster on your own, or to get computer basic training, without the help of a teacher or attending any computer class, if you’re truly in need of computer training skills to improve your computer science skills. It is better to begin your studies, with video lessons or video tutorials recorded on a simple DVD.

Choosing this method for your learning or improving your computer skills will certainly benefit you more than choosing to begin your learning with the use of books or the out-dated method of learning new computer science topics faster. This summarizes this article. I hope you enjoyed it. There are more advanced tips and lessons where I go into details on how best to improve your computer skills faster on my free newsletters at my website.

Teachers and high school students sample the water in Lake Baikal in Siberia while at other lakes around the world, other teachers and students take similar samples from local lakes and subject them to the same simple water-quality tests. Via their school computers, they exchange their results and their observations about how water pollution problems are the same around the world. They are part of a “global laboratory” project that includes scientists specializing in water pollution.

A similar computer network pins citizen activists, joined with students, teachers and scientists, in “sister watershed” groups throughout the world.

Amateur birdwatchers and biologists pool their rare bird sightings in a North American computer network that is linked with bird researchers in Central America and South America.

The differences between classroom and community education are blurred on the global computer networks. Voluntary organizations, government agencies, students and teachers are all involved in a real that has become, for many, a virtual classroom, without walls, and increasingly without borders.

Already, pilot projects have high school students sharing the methods and results from field studies of environmental quality, using computer telecommunication to leap national boundaries. Elementary school children share their life experiences end visions of the future the same way. Their messages to one another, passed with tremendous speed and shared simultaneously among many classrooms, provide strong, personal lessons in science, geography and human relations.

Environmental education curriculum development, pursued independently and often in isolation by teachers, school districts and universities over the past two decades, is now linked in a global forum that can respond immediately to the ever more complex and urgent environmental problems the world faces. Teachers the world over are connecting with their counterparts to discuss how they can do their jobs better. Co-ordination of international education projects is less burdened by the constraints of time and travel budgets as computer networks provide forums for collaboration.

The technology for this exchange takes advantage of the personal computer’s ability to communicate over standard phone lines using a modem. The simplest networks connect personal computers in a “store-and-forward” system that echoes messages from one to the next, until all have copies. These least-cost networks are linked to larger, faster computers that act as central information storage banks and relay stations. They in turn exchange information with one another and tap the power and data in computer systems at major research and educational institutions.

In many ways this vast new sea of information presents its own challenges, often akin to “drinking water from a fire hose.” The enormous glut of fact and opinion is impossible to take in, and has forced those who would taste its power to devise new ways for organizing and sampling the information flow.

Electronic mail services and computer “conferencing” let students and teachers communicate with each other privately, or publicly as members of large discussion groups. Computer conferences are organized much like those where people meet face-to-face, except that the meeting rooms are inside each participant’s computer. Computer conferences transcend time zones, since participants review and comment on each others’ written postings as their time and interest allows. Everyone gets to read and think about questions or statements posed in a conference, and everyone has a co-equal opportunity to reply.

Computer networking is making classroom walls disappear. Real environmental problems are entering the classroom with immediacy via computer nets, and students are jointly seeking understanding and solutions with scientists, citizen activists, journalists, government officials and community leaders of all kinds. While access to computer networks is still remote for most people on the planet, it is becoming more and more available to the gatekeepers and opinion-leaders who help shape common understanding of the global situation. The increasing abundance of the multiple information sources available via computer networks, if viewed as a well-stocked marketplace, may also stimulate demand for more and better goods by the world’s information consumers.

Citizen participation in the 1992 United Nations Conference on Environment and Development (UNCED), for example, has been ccoordinated via computer networks on seven continents, giving NGOs access to complete text of the preparatory committee documents, and providing public forums for news and issue discussion. This availability of information has a dramatic effect on how an event such as UNCED permeates the mass media everywhere.

Underlying the often chaotic view presented by the mass media, structures are developing to channel the new rivers of information to empower this and coming generations to deal with the issues it describes. A variety of efforts at computer networking for environmental education provide some great models. At the root, these efforts are all based on the same notion: that environmental problems must be viewed with a global perspective, but responded to by individuals acting locally, in their own communities or homes.

All of this new technology is not without cost, and the developed countries are clearly ahead in providing computer access for education. But even in the United States, where computer telecommunication is becoming commonplace, profit rather than educational reform is a dominant force in determining who gets access.

The harsh reality has motivated citizen computer networks to band together in the international Association for Progressive Communications (APC) to make computer network access broadly available. The APC hosts several promising educational efforts on its partner computer networks that now extend to more than 90 countries around the globe. These services may be tapped by anyone with a personal computer and modem, often via a local call, at costs roughly equivalent to a newspaper subscription or monthly telephone bill.

The education projects offered on the APC networks are examples of how low-budget computer communication can fit into community programs and classrooms.

To keep computer systems in top performance you will need to know the risks, and what you can do to protect yourself from viruses and computer hackers.

Our world today practically relies on the computers and the Internet. A massive attack on of a computer virus could wipe out communications, air traffic control, hospitals and credit cards. Specialists with training in computer and network security are needed to help us protect this information by preventing, detecting, and responding to attacks.

As Security risks are becoming greater, qualified people are needed to keep computer networks secure. You can learn to defend computer networks against scams, fraud, espionage and more when you earn a degree in computer network security.

This course of study will teach students how to install, maintain, and monitor existing security software for both the private and public sectors. Students will be able to build computer security programs, fix existing programs, install security software, and be able to recognize when an intruder is attempting to hack into a computer network.

Jobs in network security cover many different areas. Here are some jobs in Computer Network Security:

· Database administrators work with database management systems software and determine ways to organize and store data. They identify user requirements, set up computer databases, and test and coordinate modifications to the computer database systems. They basically manage and protect a company’s data.

· Computer Systems Analysts solve computer problems and apply computer technology to meet the individual needs of an organization. Systems analysts may plan and develop new computer systems or devise ways to apply existing systems’ resources to additional operations. Computer systems analysts use the computer’s technical abilities to meet the needs of a particular type of industry or company.

· Network Administrators and Computer System Administrators oversee network security as part of their jobs. They also design, install, and support an organization’s local-area network (LAN), wide-area network (WAN), network segment, Internet, or intranet system. They also provide day-to-day onsite administrative support for software users in a variety of work environments.

· Computer Security Specialists are employed for the sole purpose of working on computer security for a company. These specialists plan and implement computer security for an organization. They may also train others in computer security, install computer security systems, and monitor networks for breaches in security. They may even be called upon to respond to cyber attacks, and even collect data and evidence to be used in prosecuting perpetrators.

These careers are expected to continue to grow according to the U.S. Department of Labor. Salaries in this industry range from $58,190 to $66,460.
